Cross-Validation and the Estimation of Conditional Probability Densities
- Journal of the American Statistical Association
, 2004
"... ABSTRACT. Many practical problems, especially some connected with forecasting, require nonparametric estimation of conditional densities from mixed data. For example, given an explanatory data vector X for a prospective customer, with components that could include the customer’s salary, occupation, ..."

of conditional inference. For example, if the jth component of X is independent of Y then that component is irrelevant to estimating the density of Y given X, and ideally should be dropped before conducting inference. In this paper we show that cross-validation overcomes these difficulties. It automatically

B(H) lattices, density, and arithmetic mean ideals, preprint
"... Abstract. This paper studies lattice properties of operator ideals in B(H) and their applications to the arithmetic mean ideals which were introduced in [10] and further studied in the project [14]-[18] of which this paper is a part. It is proved that the lattices of all principal ideals, of princip ..."

Ultrafilters and two ideals on ω
"... Abstract. Two classes of ultrafilters on natural numbers are presented which are determined by the summable ideal and the density ideal. The relationship between these two classes is shown and also the relationship to the well-known class of P-points. Under some additional set-theoretic assumptions ..."

Notes on the ideal (a).
"... We consider for any topologies τ1 ⊆ τ2 the ideal of sets A such that for each nonempty U ∈ τ2 there exists W ∈ τ1 such that U ∩W 6 = ∅ and A ∩ U ∩ W = ∅. For τ1 the standard Euclidean topology and for τ2 the density topology we obtain investigated by Z.Grande and E.Strońska the ideal (a). 1 Notatio ..."

The ideal conductor limit
, 1995
"... This paper compares two methods of statistical mechanics used to study a classical Coulomb system S near an ideal conductor C. The first method consists in neglecting the thermal fluctuations in the conductor C and constrains the electric potential to be constant on it. In the second method the cond ..."

1. – The ideal Fermi gas
, 2007
"... We consider in this section a non-interacting Fermi gas in a single spin component, at thermal equilibrium in the grand canonical ensemble. We review basic properties of such a gas. We concentrate on the degenerate regime ρλ 3 ≫ 1, with ρ the density and λ the thermal de Broglie wavelength defined a ..."

An Approximate Kalman Filter for Ocean Data Assimilation; An Example with an Idealized Gulf Stream Model
, 1995
"... A practical method of data assimilation for use with nonlinear, ocean general circulation models is explored. A based on approximations of the state error matrix is presented, a reduction of the effective model dimension, the error's asymptotic steady-state limit, and a time-invariant lineariza ..."

We examine the utility of the approximate filter in assimilating different measurement types using a twin experiment of an idealized
COVERING PROPERTIES OF IDEALS
"... M. Elekes proved that any infinite-fold cover of a σ-finite measure space by a sequence of measurable sets has a subsequence with the same property such that the set of indices of this subsequence has density zero. Applying this theorem he gave a new proof for the random-indestructibility of the d ..."

-indestructibility of the density zero ideal. He asked about other variants of this theorem concerning I-almost everywhere infinite-fold covers of Polish spaces where I is a σ-ideal on the space and the set of indices of the required subsequence should be in a fixed ideal J on ω. We introduce the notion of the J-covering property
